SECTION 1. ANALYZER OPERATION - ALL
NOTE:
This manual is intended as a supplement to the indi-
vidual machine’s Operators and Safety Manual.
1.1 INTRODUCTION & OPERATION
NOTE:
It is the responsibility of the
owner/user/operator/les-
sor/lessee
to read & understand this manual and the
machine Operators & Safety Manual and to prevent
overloading the platform. Do not operate a machine
with a disconnected or inoperative Load Sensing
System.
The JLG-designed Load Sensing System (LSS) measures
platform load. If the actual platform load exceeds the
selected Rated Load, the following will occur:
1. The Overload Visual Warning Indicator will flash at
the selected control position (platform or ground).
2. The Platform and Ground Alarms will sound 5 sec-
onds On, and 2 seconds Off.
3. All normal movement will be prevented from the
platform control position (optional - ground control
functions may be prevented).
4. Further movement is permitted by:
a. Removing the excess platform load until actual
platform load is less than Rated Load.
b. By an authorized person at the ground control
position (optional - ground control functions
may be prevented).
THE LOAD SENSING SYSTEM MUST BE CALIBRATED WHEN ONE
OR MORE OF THE FOLLOWING CONDITIONS OCCUR:
a. LSS System initial installation
b. LSS Module replacement
c. LSS Sensor removal or replacement
d. Addition or removal of certain platform mounted
accessories. (Refer to Calibration in Section 2)
e. Platform is removed, replaced, repaired or
shows evidence of impact.
THE LOAD SENSING SYSTEM REQUIRES PERIODIC FUNCTION
VERIFICATION NOT TO EXCEED 6 MONTHS FROM PREVIOUS
VERIFICATION. REFER TO TESTING & EVALUATION IN SECTION
2.
Calibration of the Load Sensing System is performed by
connecting the JLG Analyzer (Analyzer Kit, JLG part no.
2901443). All calibration procedures are menu driven
through the use of the Analyzer.
1.2 USING THE ANALYZER
